Canned foods are often loaded with excess sodium and other preservatives to prolong their shelf life, which can have negative effects on health, especially in the case of frequent consumption.
Too much sodium can have negative effects on blood pressure and other heart conditions and can also lead to water retention, which can cause inflammation.
About 10% of canned foods still contain foods that contain chemicals, and if consumed regularly, are associated with high blood pressure and can even increase the risk of cancer.
When buying canned foods, make sure that they do not contain BPA (bisphenol A).
It is important to note that the study only showed that BPA causes a temporary increase in blood pressure.
It is a chronic high blood pressure that puts more strain on the walls of the arteries and veins, which is often associated with doctors.
However, it will require a different study design to determine whether BPA has a long-term effect on blood pressure.
Even a temporary increase in blood pressure can lead to a stroke or heart attack in high-risk patients.
Risk of lethal bacteria present in cans
This is a controversial topic regarding the safety of canned food. However, harmful bacteria are rare in cans. This only happens when the process fails or does not follow the standard SOP, leading to the growth of bacteria such as Clostridium botulinum, which can cause dangerous infections.
Eating such contaminated food can cause botulism, which can lead to paralysis or death if left untreated. Most health problems are related to home-canned food.
The sale of canned food rarely causes botulism. However, prepare food from a damaged or broken can.
Health risks associated with preservatives present in canned foods
Depending on the expected shelf life and the type of food, sugar, salt, and other preservatives are often used in canning. This explains why canned foods often taste salty. While this is not a health risk for most people, it can be a problem for those with underlying conditions such as high blood pressure.
However, any form of added sugar is never good for health. It is associated with the development of chronic conditions, including heart disease, obesity, type-2 diabetes, mental retardation, non-alcoholic fatty liver, and some types of cancer.
